Q: When should I mow new sod?

ANSWER:

You can mow new sod as soon as the roots start to grow or when it is anchored to the ground, so that it won’t lift up. Do not remove more than 1/3
of the blade of grass at one cutting. It is better to mow more frequently to get to the desired height, than to remove too much at one time.

It is also important to keep new sod a bit longer in length until the roots become more established. This will allow the grass to focus on root development,
rather than recovering from a cutting. Keeping the grass longer will also help to keep the sod from drying out as fast.

A good grass height is 3 inches. This length helps to reduce evaporation and is a healthy height for residential lawns.
